gistfile1.m

- (void)handleSwipeLeft:(UISwipeGestureRecognizer *)gestureRecognizer
{
    //Get location of the swipe
    CGPoint location = [gestureRecognizer locationInView:self.tableView];

    //Get the corresponding index path within the table view
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:location];

    //Check if index path is valid
    if(indexPath)
    {
        //Get the cell out of the table view
        UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];

        //Update the cell or model
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
}

- (void)handleSwipeRight:(UISwipeGestureRecognizer *)gestureRecognizer
{
    //same code for getting UITableViewCell like before
}
